Charles Schwab, which is relatively high, charges $8/trade (for unmanaged trades).

$8 per tx seems like a very high fee for cryptocurrency transactions.

It’s really not. Gdax charges 0.25% (only to one party, so let’s call it 0.125 on average). You only have to buy less than $10,000 worth before the fee is higher than $8

And Gdax is totally required to charge their index fund customers that 0.25%?

I figured that the comment I was originally responding to made it sound like transaction costs are a technical reason for the management fees being high.

A good example would be ~$10 per trade to buy any quantity of stock.

You seem to be confusing transaction costs and management fees

How do you mean? I’m very aware of the difference between the two.

Robinhood charges zero
